If you want to improve your chance of getting a date on any online dating site, you should wear a red shirt. Slate took a look at various studies comparing the same person wearing different colored clothes and each time, red was the most successful color. Do it. Change your online profile now.

It's like the secretly effective scarlet letter. One study showed a picture of the same woman bordered in different colors and the picture bordered in red was found to be more attractive and sexually appealing. It was the same woman! Another study showed 64 women on online dating sites. Their shirt was rotated between six different colors and red won out again. Slate says:

Twenty-one percent of their emails arrived when they wore red, whereas the other colors-black, white, yellow, green, and blue-attracted 14 to 17 percent of the total.

Moral of the story: wear red. It works for guys too. Read more about why at Slate]
